add_info was a thing that grew organically to account for hidden
contras, but just wasn't right. The assumption was that if the
contra account is hidden, the contra itself should be hidden from
view - the sign of the amount would be wrong anyway.
The correct approach, however, would of course to flip the sign so it
matches the user's perspective, and to add a separate description string
to display to the user.
Beginning of a line was already trimmed, courtesy of the whitespace
split. The end of a line was previously not trimmed because of the limit
for split.
Replaced by 3 lines in revbank.products:
BOUNTY1 -10.00@-expenses/bounties Bedankt voor het vegen/stofzuigen
BOUNTY2 -10.00@-expenses/bounties Bedankt voor het afvoeren van het afval
BOUNTY3 -25.00@-expenses/bounties Bedankt voor het dweilen
Originally written as a proof of concept demo. Reportedly it's broken
and cumbersome to use anyway, because of the external config file.
I don't think anyone is actually using this right now.
Now implemented via a hidden user called '-cash'.
This also introduces the concept of hidden accounts, that begin with '+' or
'-', for result accounts and balance accounts. Future versions can further
use this for more detailed bookkeeping. The idea behind the sign is that
'-' accounts should be inverted to get the intuitive value. So if the account
'-cash' has -13.37, that means there should be +13.37 in the cash box (or,
well, once the rest of this is implemented and the initial values are then set
correctly.)
This should have been done much earlier, but wasn't done for nostalgic reasons.
To new users, it didn't make sense that you could just enter an amount, and
revbank would just accept that as "withdrawal or unlisted product". It existed
for backwards compatibility with the very first revbank version, which didn't
have a product list, and which was not yet used with a barcode scanner. You
would simply enter the amount and your name, and there were no further
statistics.
Nowadays, there are statistics that are messed up if you don't use the product
codes. And some people were looking for a withdrawal command, and try 'take' as
that seems closest to it, but which instead transfers money to another account.
Additionally, some texts were changed for improved clarity. ("Enter username to
pay", when withdrawing, was confusing: one expects money back, not to pay more.)
It's ~25% of our logfile.
This feature was made so you can theoretically do a replay of the log, which
requires knowing which plugins were active when. But I don't think anyone's
actually doing that because it also requires other info that isn't logged.
The signatures feature has been "experimental" since Perl 5.20 (May 2014), but
expected to stay. After 8 years I'm ready to take the risk :)
Have added Perl v5.28 (June 2018) as the minimum requirement, even though the
current revbank should work with 5.20, to see if this bothers any users. Perl
v5.28 is in Debian "buster", which is now oldstable.
